They say money is the root of all evil — or, in Leah and Jeremy’s case, some heated arguments.

In the past, the “Teen Mom 2” couple has endured some tense moments when they’ve discussed their finances. And in the sneak peek below, a conversation about their bills becomes heated when Jeremy accuses Leah of lying about what she’s been spending.

“I’m buying stuff for my job, and our bills are paid,” the mother of three calmly explains.

But Jeremy can’t contain his anger. “How ’bout lets pay s**t off that we say we’re gonna pay off for a year now, and we have yet to do it,” he says, before adding that the couple has spent hundreds of thousands of dollars in the past year. After Jeremy rattles off various charges that he’s looked up on his phone, Leah suggests counseling and insists that she’s not going to argue about money with him any longer.

“You never have faith in me — I can never do anything,” she shouts. “I’m not allowed to do anything.”
